The dog (Canis familiaris or Canis lupus familiaris) is a domesticated descendant of the wolf. Also called the domestic dog, it is derived from the extinctPleistocene wolf; the gray wolf is the dog's closest living relative. The dog was the first species to be domesticated by humans. Experts estimate that hunter-gatherers domesticated dogs more than 15,000 years ago, which was before the development of agriculture. Due to their long association with humans, dogs have expanded to a large number of domestic individuals and gained the ability to thrive on a starch-rich diet that would be inadequate for other canids.
Basenjis can run up to 30-35 miles per hour and share many distinctive traits with pariah dog types. Basenjis come into estrus only once annually similar to dingoes, New Guinea singing dogs and Tibetan Mastiffs, when compared with other dog breeds which may have two or more breeding seasons each year. They lack a distinctive odor, and are prone to howls, yodels, and other vocalizations over the characteristic bark of modern dog breeds. The breed's original foundation stock came from Congo.

Human–canine bonding is the relationship between dogs and humans. This relationship can be traced back to at least 15,000 years ago, to the Bonn-Oberkassel dog, who was found buried alongside two humans. For centuries, dogs have been considered man's best friend. This is most evident in western countries, such as the United States, where 44% of households have a pet dog.
The human–canine relationship is not necessarily always a positive one; dogs can be viewed in an extremely negative light depending on the region. On average, females tend to have more positive attitudes toward dogs as opposed to males, and studies have demonstrated that both dogs and humans release oxytocin while spending time together. This release of oxytocin is correlated with the formation of a strong social bond. Canines are capable of distinguishing between positive and negative human facial expressions and will react accordingly. Dogs appear in religions all over the world, particularly in Mesoamerican folklore and myth, signifying the deep reverence humans all over the world and throughout history have for them.
